Thanks for sharing the Oticon tech support phone #, gbdba! I’ll definitely try them next time I have a question.
The TV Adapter 3.0 streamer that I have (I think Tony said he was looking to buy one, too) basically occupies a special program mode on the OPN. If you look at the Hearing Devices setting on your iPhone, you’ll see that there’s a program mode (beside the regular ones that you already have) called “TV Box 1”. Actually since you don’t have it, you probably won’t see this program on your iPhone specifically, but I do. You basically pair your OPN to the TV Adapter 3.0 then after that it remembers the OPN. From then on, whenever you want to use the TV Adapter, you simple switch the OPN to the TV Box 1 mode and you’re connected.
The TV Adaptor 3.0 connection to the OPN has always been rock solid compared to the iPhone connection to the OPN. That’s why I have some reservation that it may be more likely that the iPhone is the culprit for the bad connection issues with the OPN, because if the cause of the connection issues is from the OPN, then why would it work so well with the TV Adapter 3.0? Besides, it does make sense that since Oticon designed the TV Adaptor 3.0 themselves, that they’re in control of whatever the protocol is between it and the OPN, while Oticon is not in control of the iPhone streaming protocol because Apple sets that protocol themselves, and Oticon can only follow it.
As for interference from the TV Adaptor 3.0 causing connection to the iPhone being spotty, I haven’t seen any evidence of that. It seems to be designed to work quite seamlessly, meaning that I can be streaming from the TV Adaptor and if something else comes through from the iPhone like a phone call or alarm, it would interrupt the TV streaming and the iPhone streaming takes priority over it. So it seems like Oticon has designed and enabled parallel operation between the TV Adapter and the iPhone to work together well up front.
